Cosmology

Cosmology is the study of the origin, evolution, structure, dynamics, and ultimate fate of the universe as well as the natural laws that keep it in order. It also includes the study of the nature of the Universe on its very largest scales.

Steven Hawking, the man with the computerized voice, has become part of pop culture, making his way into TV shows and songs. He has had a prestigious career as a cosmologist who was able to communicate the wonders of the universe despite a progressive and debilitating condition.

Cosmic Scale Factor is a function of time which represents the relative expansion of the universe. It relates the comoving distances for an expanding universe with the distances at a reference time arbitrarily taken to be the present.

The Cosmic Microwave Background Radiation (CMBR) or Cosmic Background Radiation (CBR) is the afterglow from the early universe and provides strong evidence for the theory of a hot Big Bang. This article looks at what the CBR is, how it was detected and why it is important for cosmology.

Despite the complexity of the universe, all matter is made up of a limited number of particles, and the way in which these particles interact with one another can be reduced to no more than four distinct interactions.

The accelerating expansion of the universe is the observation that the universe appears to be expanding at an increasing rate, so that the velocity at which a distant galaxy is receding from the observer is continuously increasing with time.
